IMPROVEMENT IN COAL- STQVES.

The Schedule referred to in these Letters iglatpnt and making'part ofthe same.

-ieut mode of separating the refuse products of combustion from theburning fuel above them, so that ordinary coal-fires may be perpetuatedat will.

Also, that the ash and cinder, which are the refuse products ofcombustion, may be conveniently removed at any time, without disturbingthe fire above.V

Also, to secure as favorable a draught as possible for the entireconsumption of the coal, with all its escaping combustible gas. v

I use nograte. The placeordinarily occupied by a grate, I leave n'earlyopen and free to a hopper below,

'for the reception l'of the refuse products, as they are separated fromand by the burning mass above. and 4from which hopper they aredischarged, at will, by

means of aslide' out-oij-ust beneath it.

Figure 1 is a. plan View of a common cylinder-stove, containing myimprovements.

Figure 2 is a perpendicular-middle section, and.

shows all the parts.

- a is the ash-pit, which may receive a drawer.

`b is a removable slide, shutting up the bottom of thehopper, and to beOpera-ted for the `delivery of ash and cinder past it into the asl1`pit.c is the ash-hopper, and in this instance it is attached permanently, bynarrow branches al d, to E, which is a ribbed circle, and, is hung, soas to be vibrated easily, just below the fire-chamber, by means of thehand-lever j'.

g is the lower portion of :ihre-chamber. The operation of the stove isas follows:

The draught is a side draught, h h h, in this instance extendingentirely around, and just below the fire-chamber, and occupying thespace between the top of the hopper c, and the fire-chamber, or ratherthe ribbedcircle e', which is at the base of the ire-ohaiber. than thetop of the hoppers, so as to v protect the draught from beingquicklyembanked byashe's.

Let the hopper be closed at the bottom by the slide b, andV filled.with` either ashes orfcoal, a little4 abovethe draught; then kindle there, and feed it, as usual; and whenever the ash-hopper becomes so filledand heaped up, as to obstruct the draught toomuch, the slide beneath itshould be operated to pass the required amount of its contents into theash -pit or drawer be' low. 'And if, by reason Of a self-bridgingprocess, oommon with coal-tires, the whole mass needs urging downward,it is easily done by vibrating the ring 'e by the" lever f.

I claim, as my inventionl. The ash.- hopper e, 'or its equivalent,applied as a medium of communication from thetire-chamberto the ash-pit,substantially in the manner and for the purpose herein set forth.

2. The annular or side draught, accomplished withf out a grate betweenthe ash-pit' and the. lire-chamber, and below the feed-door,substantially as and for the purpose herein set forth.

rlhe ribbed ring e', Or its equivalent, in combina tion with there-ohambcr above, and ash-hopperbelow, substantially as and for thepurpose hereinset forth.

4. The slide b, in combination with the hopper and ash-pit,substantially as set forth.
